Delay Setup Menu
• You can adjust the Center, Right Surround
and Left Surround speaker delays by pressing
the LEFT and RIGHT keys. The range of
adjustment is from 0 to 5 ms (milliseconds) for
the Center channel and from 0 to 15 ms for the
Right Surround and Left Surround channels
• You should normally position the Left and
Right Front speakers so, that they are further
away from the listening position than the
other speakers
• Setting the delay time on the center channel
speaker helps align the sound of actor’s voices
with the visual cues of their lips. For example,
if the center speaker is located behind or in
front of the video monitor, then the arrival
of the sound will not match the movements
on the screen.
You can calculate the delay times by first measuring the distance from the listening position to each speaker. At sea
level, 1 foot equals approximately 1 millisecond (20 feet equals 20 milliseconds). Enter then these measurements in
the table below. Place the Left and Right speakers at an equal distance from the listening position. Write the Left/Right
Front speaker distance down three times, in each of the boxes in the top row.
If you get the delay settings correct, the spatial perspective of the audio will be very good to excellent. If you get these
wrong (especially the center channel), then the audio perspective will be inferior. One complication . . . humans have
difficulty perceiving delays shorter than about 25-30 milliseconds. You may find that exaggerating the delay time
makes the audio sound better to YOUR ears; or maybe not. Once you set the delay times by measurement, you might
want to experiment with the time settings.
The following example illustrates the calculation of correct delays. The Left and Right Front speakers are at 10 feet,
the Center speaker is at 7 feet, the Left Surround and Right Surround speakers are at 13 feet from the listener.
